3D Piping network formation method using internal connection information and 3D pipe path tracing method

The present invention relates to forming and tracking a piping network. A virtual node or a virtual link is generated in equipment or accessories having no internal connection information in a piping network, and the piping network is connected in a repetitive structure of a link-node-link-node without disconnection. In addition, connection information is provided to all nodes, thereby enabling accurate and diverse functional piping tracking.
